Rear Suspension Support
SumoSprings helper springs are great for RVs or motor homes. Heavy rear loads can cause sag as your factory suspension compresses under the weight of the load. This means that the rear axle is trying to support not only the extra load but also the motor home's weight. And because there is less weight on your front axle, your front tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.
Each spring in this kit is bolted to two mounting brackets. One bracket is attached to the frame of your vehicle, and the other bracket is attached to the axle, typically above your existing factory leaf spring. Because each helper spring is in full contact at the top and bottom of the suspension's travel, the expanding and contracting action of the SumoSprings enhances your ride under all conditions, not just when it's loaded. And the closed-cell urethane springs act like a shock absorber to dampen road vibration.
SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The springs can also compress by as much as 80 percent to support a heavy rear load and to help your factory suspension bear up under the load. This evens out the weight, which levels your vehicle and ensures that your front tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.
The springs work independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.
These springs extend in height by as much as 50 percent to allow more movement in your suspension when you're traveling unloaded, making your ride smoother and more comfortable.
Durable, Custom-Fit Springs
These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).
SumoSprings expand and compress vertically with minimum expansion to the sides, so they won't be damaged by nearby mechanical parts and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.
This kit comes with custom-fit brackets that are designed to easily bolt onto your vehicle.

2018 Jayco Greyhawk Motorhome
I am sure these are very good, the only reason for the low rating is to get attention so no one makes the same mistake like i did.
These DONOT FIT on a 2018 Jayco Greyhawk equipped with the JRide suspension. The Heliwig helper springs are in the way.
etrailer application guide needs to be updated, the picture attached show the Heliwigs are in the way.

2019 Thor Outlaw 29J I've only driven this RV for about 1800 miles.
I don't know if I could rate these any higher. I ordered both the front and rear Sumosprings and the fronts arrived earlier than the rear, so I went ahead and installed them and went for a 100 mile test drive. Night and day difference, no more harsh ride in the front, and a lot less pogoing. Now I can't wait until the rears come in and I can test those.
by: Michael09/16/2020
Added these rears and also did fronts at the same time. Did the install myself. Took longer than I thought it would, but not bad if you have some mechanical ability. If you do be very careful while drilling the holes on the drivers side as the instructions state, the brake lines are right there and if you don’t put some kind of block between the lines and frame you may damage those lines. Adding the front and rears has improved the handling of driving our motorhome greatly. Just drove 800 miles since installing and the stress from driving was so much less. Hardly noticed the winds and semi’s. Would recommend this product.

The use of this Sumo springs has greatly cut down the sway of Thor Chateau motor home with Ford E350 chassis. Very glad to have installed them. Strongly recommend them for any RV’er who has difficulty with driving any motorhome due to sway.
by: Larry 08/16/2020
A bit harder to install with the dual tires on but followed the instructions and had no issues with the installation. Felt the difference the first time out. Courtney was great to work with, recommend that you go to her for help.

I have a 28-foot-long class A motorhome on a Ford F53 Chassis. The handling of the vehicle at any speed above 50 mph is terrible. The vehicle wanders all over; very difficult to keep the vehicle between the lane marker lines. The SumoSprings, installed front and rear, did not solve this problem. Money would have been better spent elsewhere!
by: Frank S05/12/2023
Front and rear Sumo Springs installed. Have not had a chance to hit the highway as yet. Locally a very good ride. Thanks to Joanne K. for all of her help.
by: Philip 08/30/2022
As always, eTrailer service and delivery was flawless for me on these SumoSprings for my 2021 WBGO Adventurer 29B Class A. Installation was done by a local WBGO dealer, who noted that it was easy and relatively quick to accomplish. My reason for getting the SumoSprings was to reduce rear body sway in turns and due to wind buffeting. For this, they seem to work well -- there is noticeably less sway now than before -- which is more confidence-inspiring and takes some of the effort out of dealing with passing trucks or brisk gusts of wind (especially from the side). However, as with any suspension modification that effectively stiffens the suspension, the sway reduction is accompanied by a somewhat harsher ride. This is especially noted when crossing bumps, train tracks, and expansion joints. For me, it's an acceptable compromise, after all, the RV is still a truck and will always ride and handle like one.
by: Joseph05/20/2022
I had these sumosprings installed on my class A motorhome 1yr ago to eliminate role. I have been extremely pleased to experience a 90% reduction in role and a MUCH smoother ride. The motorhome is easier to drive and maneuver single handed, even in the turns.
by: Joe 04/10/2024
My motorhome drives great and does not sway bad anymore. I also added Michelin tires which made the ride even better!
by: David01/04/2024
Greatly improved ride and handling. Had to re-plumb gray tank drain around spring.
by: Rex05/02/2021
I watched the install video probably three or four times before these arrived at the house. I went ahead and removed my wheels just like the install video. Everything went smoothly. I took our Fleetwood Flair 32s on a test drive and I was really impressed with the overall feel of our RV now.. The first thing I noticed was the fact that I’m not having to constantly correct to stay in my lane. In the past my hands were constantly moving to maintain a line. Not now.

- Recommended Rear Suspension Enhancement For a 2023 Ford E-450 Class C Cutaway ChassisI recommend installing the SumoSprings # SSR-106-47-1 on the rear of your 2023 Ford E-450 Class C cutaway chassis. In my experience I feel these are the best option as they cushion the suspension while the Timbren # TFERSD you found is much stiffer and I find creates a harsher ride. Even with you mentioning your front riding great you should still consider the Front # SSF-106-47 SumoSprings as they will help when you get on roads of lesser quality. If you notice a lot of body roll you...

Reason why is these mount on top of the leaf spring pack so a leaf spring helper like the SuperSprings # SSA22 would interfere with the mounting. If you wanted to use SumoSprings and SuperSprings together you would have to remove the Maxim and go to SumoSprings that mount to the side of the leaf spring pack, the SumoSprings Solo...

If you don't have that clearance then you need the kit # SSR-130-54 instead for the rear part.

- Which Hellwig Anti-Sway Bars Should Be Installed on a 2022 Entegra Odyssey 26DHey Robert, thanks for reaching out! You are correct that you'll want to install the rear Hellwig Anti-Sway Bar # HE78RR first on your '22 Entegra Odyssey 26D, and then if you still need more help you can install the front Hellwig Anti-Sway Bar # HE26GR.

If you have a different chassis please let me know. The SumoSprings Solo Custom Helper Springs Front # SSF-106-40 and Rear # SSR-106-47-1 are great to add with the sway bars.
